I have an iPhone on ATT's International iPhone plan which gives me unlimited WW data. I carry a second phone with a roaming SIM or a local prepaid SIM. That phone is currently a Nokia E66 which I love. The phone is wearing out and also doesn't support North American HSPA frequencies. This is becoming more of an issue sicne roaming SIMs have stopped working on Rogers in Canada, ATT is decommissioning 2g networks, etc. I'm looking for a good sucessor.

I want wifi, at least S60 SYmbian, and a a traditional phone appearance. I don't want to be carrying two sliders. I liked my E66 because it looked like an el-cheapo phone, but supported things like VOIP, wifi/bluetooth data, and some nice dialer apps.

What would people suggest as a replacement?

This is good to find phones based on specs: http://www.gsmarena.com/search.php3

You could import a Nokia E6-00 - looks closest to the E66
